[Industrial applications]

 The invention relates to a helmet, in particular its advantageous internal structure.

[0002]

[Prior art]

 Helmets typically include a shell of rigid material, a liner of cushioning material fitted inside the shell, and an interior pad mounted on the inner surface of the liner. This interior pad has a structure that partially covers the inner surface of the liner in order to improve air permeability. It can be attached to and detached from the liner for washing, etc., and the pin for attaching the engaging member such as a hook can be projected directly from the shell or from the back plate inserted between the shell and the liner. There was something.

[0003]

[Problems to be solved by the device]

 By the way, in the case of the structure of the above-mentioned interior pad, since it does not cover the entire inner surface of the liner, the liner is partially exposed from between the interior pads and is visible to the outside. It is desirable to eliminate it. In addition, if the liner was exposed inside the head compartment of the helmet, it was easily soiled, and if soiled, it was difficult to wipe it off. Therefore, from this point as well, it was desired to prevent the liner from being exposed. However, it is also required that the interior pad can be detachably attached. The present invention satisfies the above requirements.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, a helmet according to the present invention comprises a shell made of a rigid material, a liner made of a cushioning material fitted inside the shell, and an interior pad removably attached to the inside of the liner. The inner trim having a substantially hemispherical main body that covers the entire inner surface of the liner is mounted between the liner and the interior pad, and an annular edge is formed around the opening of this inner trim. Fit the edge of the liner into the annular groove formed between this annular edge and the main body, sandwich the annular edge between the shell and the liner, and fix the inner trim with the engaging member. The internal pad is removably attached to the inner trim via this engaging member.

In the present invention, the inside of the shell, liner, interior pad, inner trim and the like means the center side of the head accommodation space in the helmet.

[0006]

[Action]

 When the inner trim is installed between the liner and the interior pad, the substantially hemispherical body covers the entire inner surface of the liner. Therefore, even if the interior pad is not covered with the interior pad to ensure air permeability, the liner cannot be seen from between the interior pads. Moreover, the annular groove also covers the edge of the liner.

Further, since the annular edge of the inner trim is fixed by being sandwiched between the shell and the liner, the engaging member is attached to the main body of the inner trim, and the interior pad is attached to and detached from the inner trim via this engaging member. Can be installed freely.

As is apparent from FIG. 2, the inside of the helmet has a structure in which a liner 5, an inner trim 6, and an interior pad 7 are sequentially stacked from the shell 1 inward. Both the liner 5 and the inner trim 6 have a substantially semicircular cross section so as to form a head accommodation space 8. However, in the interior pad 7, a part of the portion corresponding to the crown is a ventilation space 9.

Around the mounting portion of the chin strap 4, an ear housing space 10 is formed, which is surrounded by a cutout portion 11 of the interior pad 7 and an ear pad 12.

The liner 2 made of a cushioning material such as Styrofoam has a lateral ventilation groove 14 extending in the front-rear direction formed in the front edge 13 among the edges surrounding the opening, one end of which is the head of the liner 5. It communicates with a vertical ventilation groove 16 formed below the front part of the inner surface 15 which is the surface of the accommodation space 8.

On the other hand, the rear edge portion 17 is also formed with a lateral ventilation groove 18 extending in the front-rear direction, and one end of the lateral ventilation groove 18 communicates with a vertical ventilation groove 19 formed below the rear portion of the inner surface 15. .

The inner trim 6 is surrounded by a substantially cap-shaped main body 20 and the entire circumference of the opening thereof, as shown in the side view of FIG. 3 and the front view of FIG. The annular edge 21 is formed continuously and integrally.

An annular groove 22 having a width about the thickness of the edge portion of the interior pad 7 is formed between the main body portion 20 and the annular edge 21, and the edge portion of the interior pad 7 is fitted into the annular groove 22. 21 is sandwiched between the shell 1 and the liner 5, whereby the inner trim 6 is attached to the inside of the liner 5 (FIG. 1).

As a constituent material of the inner trim 6, for example, a laminated material obtained by laminating a thin foam layer of a thermoplastic resin and a skin layer formed of a sheet or film of a thermoplastic resin such as vinyl chloride is formed into a predetermined shape. The contact feeling is good and the skin layer can be easily wiped clean.

The main body 20 has a shape and size capable of covering the entire inner surface 15 of the liner, and by covering the inner surface 15 of the liner and the edge of the liner 5 with the main body 20 and the annular groove 22, 5 is not exposed in the head accommodation space 8.

Further, since the edge portion of the interior pad 7 is fitted in the annular groove 22, this portion is also not exposed to the outside.

Therefore, the appearance can be improved, and the appearance can be further improved by applying an appropriate color or the like to the inner trim 6 that is to be seen, and the appearance is far better than the color applied to the liner 5. Is improved and is advantageous. Moreover, the surface of the liner 5, which is difficult to wipe off, can be prevented from becoming dirty.

Further, from the front surface and the back surface of the main body portion 20 to the bottom portion of the annular groove 22, the concavo-convex portions 23 and 24 which are fitted into the lateral ventilation grooves 14 and 18 and the vertical ventilation grooves 16 and 19 of the interior pad 7. Are formed.

Of the uneven portion 23 on the front surface of the main body portion 20, one side 25 of a suitable engaging member such as a male member of a hook is provided at both ends, and the uneven portion 24 on the back surface is The opposite ends are provided with the other side 26 of a suitable engaging member, such as the female side member of the hook.

A vent hole 27 penetrating the front and back is formed in a portion corresponding to the forehead of the main body portion 20. Further, as shown in FIG. 6 which will be described later, the annular rim 21 can be fixed at its tip to the entire outer surface of the liner 5 by using an adhesive tape 28.

As is apparent from FIG. 3 and FIG. 5 showing the front shape of the interior pad 7, the interior pad 7 has a front part 30 which comes into contact with the forehead, a neck part 31 which comes into contact with the back of the neck, a front part 30 and the neck part. Each part of the top belt 32, which ties 31 in the front-rear direction along the top of the head, and the side part 33, which wraps around sideways, are sewn together at the connecting ends.

As described above, when the interior pad 7 is composed of independent parts, it becomes easy to adjust the size such as thickness and area.

Engaging members 34 that engage and disengage one side 25 of the engaging member are provided on both left and right sides of the front portion 30 corresponding to the one side 25 of the engaging member, and the other side 26 of the engaging member. Engaging members 35 that engage with and disengage from the other side 26 of the engaging members are also provided on the left and right sides of the corresponding neck portion 31, and these allow the interior pad 7 to be attached to and detached from the inner trim 6. .

When the interior pad 7 is attached to the inner trim 6, the annular edge 21 is sandwiched between the shell 1 and the liner 5, so that one side 25 of the engaging member of the inner trim 6 and the other side of the engaging member. The inner pad 7 can be sufficiently supported by 26. Further, the edges of the front portion 30 and the neck portion 31 can be aligned with the edges of the liner 5. Therefore, it becomes easy to take in sufficient air from the edge of the liner 5, and the air permeability becomes good.

In addition, when it becomes dirty with sweat or the like, it is easy to remove the inner pad 7 and wash it, which is extremely convenient.

FIG. 6 is an enlarged view of the mounting portion between the front portion 30 and the inner trim 6 and shows the front portion 30 in detail. As is apparent from this drawing, the inside of the vertical ventilation groove 16 is used. Then, the one side 25 of the engaging member and the engaging member 34 on the inner pad 7 side are engaged.

The engagement member 34 is attached to a pad plate 36 provided in the front portion 30, and the pad plate 36 is provided with a plurality of ventilation holes 37. In the figure, reference numeral 38 is a breathable pad, and 39 is a skin made of a raised cloth or the like. Since the neck portion 31 side has the same structure, the description thereof will be omitted.

With this configuration, the fresh air in the vertical ventilation groove 16 can be introduced into the head accommodation space 8 by using the contact plate 36 that supports the engagement member 34.

Next, the mounting structure of the ear pad 12 will be described. FIG. 7 is a view showing the mounting structure of the ear pad 12. Between the shell 1 and the liner 5 near the ear housing space 10, a substantially fan-shaped mounting plate 40 is mounted by a rivet or the like not shown. There is.

A step portion 41 is formed in the vicinity of the arc portion of the mounting plate 40 as shown in FIG. 8 which is a sectional view of the liner 5 and the mounting plate 40 in the AA line direction, and the step portion 41 and the liner 5 are formed. The insertion hole 42 is formed in a substantially V-shape between and.

On the other hand, in the ear pad 12, a part of a back plate 43 for holding the shape of the pad portion is projected from the pad portion for a long time, and two protrusions are provided at the tip of the protruding portion in correspondence with each insertion hole 42. 44 are formed. Reference numeral 45 is a hole through which the chin strap 4 is inserted.

Therefore, by inserting the two protrusions 44 into the insertion holes 42, respectively, the ear pads 12 can be attached to the mounting plate 40. Further, although not visible in the drawing, the hooks provided on the back plate 43 are attached to the mounting plate 40. The ear pad 12 can be attached by engaging with the hook 47 provided on the side.

At this time, as clearly shown in FIG. 8, since the thick portion 46 of the mounting plate 40 exists between the two insertion holes 42, each protrusion 44 is sufficiently inserted into the corresponding insertion hole 42. In that case, each protrusion 44 is positioned within its respective insert hole 42 to ensure accurate mounting of the ear pad 12.

Next, the visor 2 will be described. As shown in FIG. 1, the visor 2 is detachably attached to the shell 1 by a screw 51 with an integrally formed attachment arm 50.

A central upper end portion 2 a of the visor 2 is supported by abutting against the surface of the shell 1, and a wind guide path 52 for traveling wind is formed between a lower portion of the visor 2 and a front portion of the shell 1.

As shown in FIG. 2 and FIG. 9 which is an enlarged cross-sectional view taken along the line BB, the surface of the visor 2 also serves as an air guide surface, and the duct is provided on the upper end side slightly offset from the center to the left and right. 53 is formed.

The inlet 54 of the duct 53 communicates with a narrowed portion 55 having a slight gap between the back side of the duct 53 and the surface of the shell 1, and further extends backward from the outlet 56 (FIG. 9). ).

As is apparent from FIG. 9, ventilation holes 57 are formed through the front and back on the surface of the shell 1 facing the narrowed portion 55, and the ventilation holes 57 are formed through a ventilation passage 58 penetrating the liner 5. It communicates with the vent hole 27 of the inner trim 6.

Therefore, when the traveling wind is guided from the wind guide path 52 or the duct 53 to the throttle portion 55 and passes backward from the outlet 56, the opening portion of the ventilation hole 57 on the throttle portion 55 side becomes a negative pressure. It is expected that the air trapped inside the helmet will be sucked out through the ventilation path 58 and the ventilation hole 27, and the ventilation inside the helmet will be promoted.

Next, the chin guard 3 will be described. As is clear from FIG. 10 showing the front shape of the chin guard 3 and FIG. 11 which is an enlarged cross section taken along line C-C thereof, an inlet 60 is opened forward in the central portion, and a mud is provided inside thereof. A wire net 61 is attached to prevent invasion of the like.

On the other hand, as is clear from FIG. 1, FIG. 2 and FIG. 11, outlets 63 open in the left-right direction at the respective intermediate portions 62 on the left and right sides of the chin guard 3.

As is apparent from FIGS. 10 and 11, the outlet 63 opens at a position that cannot be seen from the front (the direction of the arrow D in FIG. 11), so it is not necessary to prevent the entry of mud or the like, rather clogging. There is no wire mesh to prevent this.

As is apparent from FIG. 11, when the chin guard 3 is formed by molding from the direction of the arrow D, the outlet 63 does not have the same draft. Must be molded in a mold.

However, in the present embodiment, as shown by the phantom line, molding is performed with the side portion widened until a draft is obtained without using a slide die, and then the side portion is formed at an original angle as shown by a solid line. Bend up to. This allows the outlet 63 to be molded with a simple mold structure.
